support for platform devices
Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead
of PCI to which Nouveau is tightly dependent. This patch allows Nouveau
to handle platform devices by:
- abstracting PCI-dependent functions that were typically used for
resource querying and page mapping,
- introducing a nv_device_is_pci() function that allows to make
PCI-dependent code conditional,
- providing a nouveau_drm_platform_probe() function that takes a GPU
platform device to be probed.
Core code as well as engine/subdev drivers are updated wherever possible
to make use of these functions. Some older drivers are too dependent on
PCI to be properly updated, but all newer code on which future chips may
depend should at least be runnable with platform devices.

Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next
Highlights
----------
Re-factoring works over the exynos drm framework.
- drm_crtc, drm_encoder/drm_connector are implemented by sub drivers
directly.
- Removing pm interfaces from each sub driver, and implementing them
at top level of exynos drm.
Add DisplayPort Transmitter driver.
- Just moving existing driver from drivers/vides/exynos into
drivers/gpu/drm/exynos.
Add new LVDS bridge driver, PTN3460.
- Placed in drivers/gpu/drm/bridge, and this device is used to transfer
image signal from DP(DisplayPort) to LVDS Panel.
So this driver will be used with DP driver moved into exynos drm.
Add parallel panel support
- With the re-factoring patch series, existing parallel panel support was
broken by moving exynos_drm_display ops into each real connector driver,
DP. So this patch series adds a new parallel panel module,
exynos_drm_dpi, for supporting parallel panel, and also adds relevant
bindings.
Some fixups and cleanups.

Now since this is init code locking is fairly redudant if it wouldn't
be for the drm core registering sysfs files a bit early. And the
locking WARNINGs nicely enforce that indeed all access to the mode

In case fbdev is initialized before any output is connected,
fb resolution defaults to 1024x768. After that any output with
bigger resolution is ignored and fbdev is not displayed.
The patch postpones fbdev initialization to avoid such situation.
